I believe the one that mentioned write relays was nostrudel. Also, I would like to learn about running a relay if you can point me in that direction. I guess in general is there a place to learn about all of these different concepts that is easyish to digest?
Ultimately, you shouldn't need to worry to much about relays unless you want to join a specific one such as a community or you want to run your own.
13 is a good number. You can explore more relays by visiting https://nostr.watch
Was the client that asked about relays Amethyst or Jumble.social ? I mentioned both today.
Amethyst supports a method called Outbox and Inbox. This is the future and makes Nostr more robust and decentralized.
Jumble allows you to browse relay feeds. It's pretty cool.

Oh! Yes, Nostrudel supports this newer concept too and has a lot of options. I believe you can choose defaults or popular relays. nostr:nprofile1qqszv6q4uryjzr06xfxxew34wwc5hmjfmfpqn229d72gfegsdn2q3fgpr3mhxue69uhhxct5v4kxc6t5v5hxs7njvscngwfwvdhk6tcpzfmhxue69uhkummnw3e82efwvdhk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsk7wj75
As for running a relay, you'll need to ask yourself what kind run. Will it be a private relay or a public relay? Let me see if I can find some guides.
Probably just a private relay for now so that I could learn the ropes.
For a private relay, I use #haven
Thanks! I'll check it out.
